How to Change Screen Brightness on Windows 11

Controlling your computer screen’s brightness can help reduce eye strain and make your battery last longer. In bright environments, you would typically want your screen to be bright as well. However, in darker environments, many prefer to lower their brightness.

This guide shows you how to change the screen brightness on Windows.

Using the Monitor’s Physical Control

If you’re using an external display (e.g., a monitor), you’ll need to use the display’s physical controls to change the screen brightness. There is usually a button on the side or front of the device.

Using Keyboard Shortcuts

The easiest way to change screen brightness in Windows 11 is using shortcut keys. These keys differ from one manufacturer to another. Usually, they are marked by a Sun symbol with plus and minus signs, and you can find them at the top of your keyboard or arrow keys.

In most cases, you must press the fn key before pressing the shortcut key to adjust your screen brightness. However, some laptops include separate keys for adjusting screen brightness, and you can simply press these buttons to alter your display’s brightness.
